GIT pull error - remote object is corrupted

Question

$ git pull

remote: fatal: object 21f3981dd35fccd28febabd96f27241eea856c50 is corrupted
error: git upload-pack: git-pack-objects died with error.
fatal: git upload-pack: aborting due to possible repository corruption on the remote side.
remote: aborting due to possible repository corruption on the remote side.
fatal: protocol error: bad pack header

Any ideas why this is failing?
When I run git --bare fsck-objects --full I just see dangling links but no broken links. Also git gc didn't help in any way. When I reclone or do pull from another clone, I don't see this error.

As Julian said see https://confluence.atlassian.com/display/FISHKB/Git+indexing+fails+due+to+bad+pack+header

It really can be a memory issue, and to make sure we don't lose the solution here it is:

git config --global pack.windowMemory "100m"
git config --global pack.SizeLimit "100m" 
git config --global pack.threads "1"
